Is there a remote desktop application which supports multiple monitors?

We mostly use Windows XP's "Remote Desktop Connection", but whenever we use it to connect to a computer with multiple monitors, even if the client computer has multiple monitors as well - the remote desktop only 'acts' as one monitor and we're forced to use half (or less!) of our available display area. Also - it completely changes the window arrangement on the second monitor.

Is there a remote desktop application that knows how to deal with this, or is this a problem inherent to Windows XP?

RDC has supported multiple monitors since 6.0. There is a 6.0 update needed for XP machines which you can download here.

Simply type:

mstsc /span

at the command line while connected.

This article is great for further information and tweaking.

BTW if you want to actually have "seperate" remote monitors (having two or more screens rather than one giant one), the only solution I have found for this is splitview, which costs $39. If anyone knows a cheaper solution, I would love to hear about it.
